To all whom t may concern:

Be tknown that I, LnwrsH. DORN, a citizen of the United States, residing at Carthage, in the county of Jasper and State of Missouri, have invented certain new and useful Improvements in' Perch-Poles, of which'the following' is a specoation, reference being had therein to the accompanying drawing. n

yThis invention provides aroost or perch for chickens or other fowls that is arranged to contain insecti'cideand to diffuse it to the "exterior at different places in order that itniay be widely disseminated and act elflciently yin destroying insects and the like,

It Vis an object of the invention to enhance the efficiency, lessen the cost, and increase the utility of devices `of this character.

When read inco'nnection with the description herein, the details of construction and arrangement of parts contemplated by the invention will be apparent from the accomp'anyingv drawing, forming partv hereof, wherein an embodiment ofthe invention is disclosed for purposes of illustration. j

While the embodiment shown now is considered a preferable one, it is to be understood that it is not the intention necessarily to be limited thereto in interpretation of the claims, as modifications within the scope of the claims can beymade without' departfrom the nature and spirit of the invention;v

Like reference-characters refer to corresponding parts in the views of the drawing, of'whicho Figure 1 is a longitudinal sectional view y of av portion of the perch-pole; Fig. 2 is an end view ofthe perch-pole; Fig. 3 is a transverse sectional View, on the line 3,-3, Fig. 1; IF ig. 4 is a transverse sectional view, on the line 4.-4, Fig. 6; Fig. 5 is a View of the perch-pole in elevation, with parts broken away; Fig. 6 is a view of the pole-tube; Fig, 'Zfis a sectional kview of an endsupport1ng stirrup ,and Fig. 8 is a view thereof in elevation. y

Having more particular reference to the drawing, 9 designates a perch-pole, which, preferably, is formed yof a length' of sheet metal rolled to substantially ycylindrical shape, yexcept at the ends, and having its longitudinal edges lapped, whereby a hollow body containing an insecticide-reservoir 10 is provided. Betweenthe lapping edges of the material thereis a slot opening to the A A'sheet-metal closing member 12 has its edges bent over the flange 11 and crimped down,yas shown at 13, whereby a fluid-tight closureA for the reservoir is formed. rlhe end member is polygonal, preferably square, 1n cross-section. Y

To support the perch-pole at each end, there is provided a stirrup 14, which yis formed of sheet. metal.y The stirrup comprlses a web portion 15, corresponding in shape to the end of the pole, and it has its bottom and'side edges slitted at the corners, as shown at 16,A and turned over and inwardly to form lapping flanges 17 sufficiently removed from the web to permit the end member 12 tobe slipped between them and the web. The upper portion of the web is extended substantially horizontally and then downwardly as flanges'18 and 19, respectively, which are adapted to engage the top of a member 20 of a chicken-house, rack, or the like, whereby the stirrup is Xedly supported, a nail, screw, or the like 21 holding the stirrup down in place. VT he end member 12 of the pole is'slipped into the stirrup with its side and bottom edges under the ianges 17, kwhereby the pole is supported, and the angular formation of the parts pre- Vents the pole from turning. When it is" desired to remove the pole, it is lifted out of the stirrup at each end.

At intervals along the cylindrical portion y of the perch-pole, it is wrapped'with and encircled by absorbent wicking 22, a portion of which is led between the laps ofthe material and down to the bottom of the reservoir in the pole.y The cylindrical portion of the pole and the wicking 22 are covered with" any other suitable non-absorbent material.

Preferably the absorbent covering 23 and the sheath 24 are longi strips of material helically wound on the pole.

In orderto prevent insects from getting i v onto the perch-pole from thestirrup, the j polygonal end portions of the pole are,

fi'tect thewicking 25 and the 'filling-tube?? s onal ends.

wrapped with soft wicking 25, which lextends through the laps ofthe pole down into the reservoir. A'This wicking is held in place by clamps 26. a

Liquid Yin excessof what can be absorbed vby the wickingwill make its way to thev dep whi'c'h'constitute an overflow-drip.
